Data Manipulation: Runtime Data Manipulation
Other sub-techniques of Data Manipulation (3)
| ID | Name |
|---|---|
| T1565.001 | Stored Data Manipulation |
| T1565.002 | Transmitted Data Manipulation |
| T1565.003 | Runtime Data Manipulation |
Adversaries may modify systems in order to manipulate the data as it is accessed and displayed to an end user.[1][2] By manipulating runtime data, adversaries may attempt to affect a business process, organizational understanding, and decision making.
Adversaries may alter application binaries used to display data in order to cause runtime manipulations. Adversaries may also conduct Change Default File Association and Masquerading to cause a similar effect. The type of modification and the impact it will have depends on the target application and process as well as the goals and objectives of the adversary. For complex systems, an adversary would likely need special expertise and possibly access to specialized software related to the system that would typically be gained through a prolonged information gathering campaign in order to have the desired impact.
Procedure Examples
| Name | Description |
|---|---|
| APT38 |
APT38 has used DYEPACK.FOX to manipulate PDF data as it is accessed to remove traces of fraudulent SWIFT transactions from the data displayed to the end user.[1] |
Mitigations
| Mitigation | Description |
|---|---|
| Network Segmentation |
Identify critical business and system processes that may be targeted by adversaries and work to isolate and secure those systems against unauthorized access and tampering. |
| Restrict File and Directory Permissions |
Prevent critical business and system processes from being replaced, overwritten, or reconfigured to load potentially malicious code. |
Detection
Inspect important application binary file hashes, locations, and modifications for suspicious/unexpected values.
